Energy saved
The Capital city of India, Delhi's power demand fell by 1000MW. The ?phenomenal? dip is attributed to the Earth Hour observed by Delhi on Saturday evening and the rain that brought the mercury down by a few notches. [9]
The Canadian province of Ontario, outside of Toronto, saw a decrease of 6% of electricity while Toronto saw a decrease of 15.1% (nearly doubled from 8.7% the previous year) as many businesses darkened, including the landmark CN Tower [10]
Swedish electricity operator Svenska Kraftnät recorded 2.1% decrease in power consumption from its projected figure between 8 p.m. and 9 p.m. The following hour, the corresponding number was 5%.[11]
This equals the consumption of approximately half a million households out of the total 4.5 million households in Sweden.[12]
According to Vietnam Electricity Company, Vietnam electricity demand fell 140,000 kWh during Earth Hour.
In Ireland, the equivalent of 700,000 lights went off for the hour, leading to electricity consumption dropping 2 percent for the hour. Total electricity consumption dropped by about 70 megawatts during the period, resulting in a saving of 30 tonnes of CO2 emissions. This compares to the 50 megawatts saved during 2008's Earth Hour.[13]
